The excellent mechanical properties and its lightness make graphene a revolutionary material as efficient audio transducers for speakers and headphones. Several studies have reported the superior performance of graphene diaphragm in electrostatic and thermoacoustic transducers [1-2]. However, these graphene diaphragms are produced from expensive methods with low scalability and are not suitable for application in the more popular mechanical transducer.
ORA has developed a unique audio solution based on the use of graphene oxide (GO), an oxidized graphene produced by a scalable chemical method [3]. GO shows a good balance of stiffness, density and damping [4-5] when assembled into micrometers thick layered structure and has been shown to perform significantly better than commercial diaphragms by ORA. The biggest current challenge is to further decrease the production time and cost to an industrially viable level while maintaining the structural ordering and properties of the diaphragm.
